SPECIFICATION formingpart Of Letters Patent N0. 472,723, dated April 12,1892.

Application filed November 24, 1891. Serial No. 412,998. (No model.)

To all whom it may concern.-

Be it known that I, FRANK BERG U sT, a citizen of the United States,residing at Beloit, in the county of Rock and State of lViscousin, haveinvented a new and useful Improvement in Fastenings for Tank-Bands, ofwhich the following is a specification.

My invention relates to fastenings for tankbands; and it consists in anovel form of lugs constructed with inclined side grooves to receivemovable rollers, which will be drawn along within said grooves when thelug-rod is screwed up, and thereby firmly tighten the baud, all ashereinafter fully described, illustrated in the drawings, andspecifically pointed out in the claim.

Referring to the accompanying drawings, in which like letters ofreference point out similar parts in, each view, Figure 1 is aperspective view of a lug embodying my invention, showing part of atank-band therein and a portion of the lug-rod and its operative nut.Fig. 2 is an inside view of one of the sides of the device. Fig. 3 is aview representing two ends of the band coupled according to myinvention.

In the drawings, A is the lug, having sides a, bottom a, and back piecea the latter provided with orifice o. to receive. the rod R, which rodis screw-threaded part of its length and is supplied with threaded nutb, for a purpose presently set forth. Said back is also supplied with aslot a for passage therethrough of the tank-band.

continuous trapezoidal recess or grooved way G. As illustrated in thedrawings, the lower limit of said groove is in a right line along andfollowing the plane of the upper surface of the bottom a and extendingthe full length thereof, while the upper limit 9 of said recess inclinesobliquely from front to rear, thus forming a grooved way that graduallytapers from front to rear of the device.

B is the tank-band, the ends of which in practice are introduced throughthe slot within the lug and lie flatly on the bottom a. Looselyoverlying said band transversely are rollers L L, the opposite ends ofsaid rollers being inserted within the grooved ways G.

In Fig. '3 of the drawings I show opposite Each side aupon its innerface is cut away to form a ends of a tank-band coupled together, saidfigure illustrating a single lug constructed according to my invention;but in practice preferably two lugs are employed, that the terminal-endsof the band are respectively introduced within a lug A. and that thenrollers L are placed upon said band, their opposite ends being insertedwithin grooves G.

When the threaded nut is turned upon the rod B, it will have the effectof drawing the opposite lugs together, causing. the rollers L to turnaxially within the grooves from the wider toward the narrower endthereof. The effect will be that said rollers will press down upon thesurface of the band B and securely wedge it down upon the bottom of thelug. The closer the two lugs are drawn together the greater'will be thegrip of the band by compression of the rollers thereon as their endsprogress alongthe wedge-shaped grooves G at the opposite sides a. Toloosen the grip, the nuts I) are reversed upon the rod R, and therollers L will thus be released from tension and can be turned towardthe larger end of the grooves.

From the foregoing description, in connection with the drawings, thenature and object and practice of my invention will be readilyunderstood by all familiar with analogous devices.

Having now fully described my invention and the manner of its operation,What I claim, and desire to secure by Letters Patent of the UnitedStates, is

A tank-lug having a flatbottom a, opposite sides a, uprising at rightangles thereto, each of said sides having upon its inner face the fulllength thereof a trapezoidal recess G, and a transverse back piece afirmly connecting the two sides, said back piece oriticed for receptionof a rod Rand further provided with slot a for free passage of tank-bandB, all in combination with transverse movable rollers L, the oppositeends of which loosely lie within the side recesses, as and for thepurpose intended, substautially as described.

FRANK BERGQUIST.
